When searching for clubs using the club search page, you must input a name in the "club name" field if you filter by sport type. This restricts the ability to view all clubs by sport type. I would like to be able to do that (how should I know the name of a club beforehand, isn't the point of the search to findclubs).
This could be patched extremely quickly by making the default (empty field) return a wildcard character (which is likely how it's already implemented when not filtering by sport).
While we're at it, it would be nice to be able to sort the clubs (such as by membership or by distance from a location), but that is secondary.
